Cortador de foice agrícola

Um cortador de grama agrícola, também conhecido como cortador alternativo ou cortador de dedo, é um tipo de equipamento agrícola ou de paisagismo usado para cortar grama, feno ou outra vegetação. Consiste em uma longa barra horizontal com lâminas pequenas e afiadas fixadas em intervalos regulares. A barra normalmente é acionada por uma fonte de energia, como uma tomada de força (PTO) de um trator ou um motor elétrico.

O cortador agrícola com barra de foice opera por movimento alternativo, onde a barra se move para frente e para trás em um plano horizontal. À medida que as lâminas se movem pela vegetação, elas a cortam com uma ação semelhante a uma tesoura. A vegetação cortada é normalmente deixada em leiras ou fileiras no solo para posterior coleta ou secagem.

Os cortadores de grama com barra de foice são conhecidos por sua versatilidade e capacidade de cortar grama alta, ervas daninhas e arbustos leves em vários terrenos. Eles são comumente usados ​​em aplicações agrícolas, como produção de feno ou manutenção de pastagens, bem como em paisagismo e manutenção de estradas.

Em comparação com os cortadores rotativos, que usam uma lâmina horizontal giratória, os cortadores agrícolas com barra de foice tendem a fornecer um corte mais limpo e são mais adequados para terrenos acidentados ou irregulares. Também são preferidos no corte de vegetação alta ou fibrosa, pois o movimento alternativo permite um melhor corte e descarga do material cortado.

How Does the Agricultural Sickle Bar Mower Work?

1. Cutting Mechanism: The primary component of a sickle bar mower is a long bar with a series of sharp triangular teeth or blades. These blades are attached to a reciprocating mechanism that moves them back and forth in a scissor-like action. This movement enables the blades to cut vegetation cleanly and efficiently.

2. Drive System: The reciprocating motion of the sickle blades is typically driven by a PTO (Power Take-Off) from a tractor. The PTO transfers power from the tractor’s engine to the mower, allowing the blades to move back and forth at a high speed.

3. Attachment to Tractor: Sickle bar mowers can be attached to the tractor in different ways, depending on the design. Some models are pulled behind the tractor, while others are mounted on the side or front, allowing for greater maneuverability and ease of use.

4. Cutting Height Adjustment: The height at which the sickle bar cuts can usually be adjusted to suit the specific needs of the crop being harvested. This adjustment ensures that the vegetation is cut at an optimal height for regrowth or for baling purposes.

5. Safety Features: Given the sharpness of the blades and the speed at which they move, sickle bar mowers typically come with safety features to protect the operator and bystanders. These may include guards over the cutting bar and safety shut-off mechanisms.

6. Efficiency and Application: Sickle bar mowers are known for their efficiency in cutting through thick vegetation without tangling or clogging. This makes them ideal for harvesting hay and for maintaining areas like ditches and embankments where other mowers might struggle.

Overall, the sickle bar mower’s design, characterized by its simplicity and effectiveness, has made it a longstanding and valuable tool in agricultural practices, particularly for haymaking and the maintenance of large grassy areas.

How to Install the Agricultural Sickle Bar Mower to Tractor?

1. Read the Manuals: Before starting, read both the tractor’s and the mower’s instruction manuals. These manuals will provide specific instructions and safety warnings pertinent to your equipment.

2. Inspect Equipment: Check both the tractor and the mower for any damage or wear. Ensure all parts are in good working condition.

3. Position the Tractor and Mower: Park the tractor on a level surface and turn it off. Position the sickle bar mower so that it’s aligned with the tractor’s mounting points or hitch.

4. Attach the Mower: For a three-point hitch setup, align the mower’s hitch points with the tractor’s lift arms and top link. Secure the lift arms and top link to the mower’s mounting points using the appropriate pins and locking devices. If the mower attaches via a drawbar, align the mower with the tractor’s drawbar and secure it using a hitch pin.

5. Connect the PTO Shaft: Slide the PTO (Power Take-Off) shaft of the mower onto the PTO stub of the tractor. Ensure it locks in place.
For safety, ensure the PTO shield is in good condition and properly installed to prevent entanglement.

6. Check Hydraulic Connections: If the mower uses hydraulic systems for lifting or adjusting the cutting bar, connect the hydraulic lines to the tractor’s hydraulic outlets.

7. Adjust the Cutting Height: Set the desired cutting height according to the instructions in the mower’s manual. This might involve adjusting the length of the top link or setting the height on the mower itself.

8. Safety Check: Double-check all connections, pins, and locking devices to ensure they are secure. Verify that the PTO shaft is properly shielded.

9. Test the Mower: Start the tractor and engage the PTO at a low RPM to test the mower. Watch for any unusual vibrations or noises. Raise and lower the mower to ensure the hydraulic or mechanical systems are working correctly. Disengage the PTO before making any adjustments or if any issues are observed.

10. Use Safety Gear: Always wear appropriate safety gear, such as hearing protection, eye protection, and sturdy shoes, when operating the mower.
